Rust Iron Stains coming through tile/grout

Where my spa wall meets the pool wall, there is brown rust stains which i assume is rust from reobar. I posted on a facebook site and got a good suggestion but looking more feedback before I start fixing. See photo.

I'm in Australia so the suggestions were products supplied with AU. Suggestion was to remove the tiles around damaged spot, dig into masonry, and seal the leach area with FERROPRE epoxy. Suggestion was to also use a product called GALMET on the ipacted reo before the epoxy. Once all done, use a pool tile glue to put tiles back.

Whilst doing the repair I will need to drain water a little. How do I keep the pump running for a few days whilst the levels are low, can I simply connect my skimmer plate and hose and feed the hose from the pool if my water line is lower than skimmer box (allowing the pump to keep recirculating)?

Any help with the repair would be most appreciated.

If all you have is a skimmer (no drain), you'll have to improvise to keep the pump primed. If you run a hose from the skimmer plate and can still maintain good suction without pulling air, that will work. Otherwise, you could disconnect the pipe at the pump and run a hose directly to the pool like a long straw and bypass the skimmer altogether. A final thought would be to increase your FC to SLAM level (see FC/CYA Chart) and let it ride un-circulating for 2-3 days. You're approaching cooler weather soon no? Water temp still above 70 degrees over there?

As for the method to repair the suspected rust/rebar area, that's a bit outside my zone. But @bdavis466 can probably help.

Hi All - Thanks for the comments. Yes I have a drain in the SPA and in the POOL., there is no option for skimmer, but suspect its always pulling water? I currently have the valve set to pull from the pool, and on the weekend put in my new skimmer plate and definitely it was pulling from the skimmer so unsure if I can actually turn the skimmer off?
Does this mean water can be below the skimmer in my setup?

My water is around 80 Fahrenheit (converted from C). I was thinking it might be best to repair this once Im in winter?

I would us a gizmo in the skimmer to make the main drain do all of the "work" BUT keep an eye on the pump to make sure your main drain does work.

Do you mean block off the skimmer completely? I assume I would need to thoroughly remove all leaf debris to stop the main drain clogging?

HI Pat, If I go to SLAM level, whats the normal process to reduce FC? Just stop the SWG and keep the cover off?

Yes all leaves and stuff needs to be out of the pool. The idea behind blocking the skimmer is to keep it from sucking air to the pump. This will force the pump to pull from the main drain.
